Embodiment 1

[0089] Example 1: Taking the Yingcheng Formation of deep volcanic rocks in the Xujiaweizi fault depression of the Songliao Basin as an example, using the preprocessing method of CT images of volcanic rocks and the threshold segmentation method of binarization of 3D reconstructed bodies to realize 3D reconstruction of CT images of volcanic rocks The binarization of the volume, the specific steps are:

[0090] (1) CT sample selection of volcanic rocks: comprehensively considering the characteristics of various volcanic rocks in the Xujiaweizi fault depression, select representative rock samples (from eruptive facies, eruptive facies, immersion facies, volcanic channel facies and volcanic sedimentary facies) Among the five lithofacies, select the lithofacies / lithology that has a greater relationship with oil and gas distribution), and the representative rock samples in this study area include volcanic breccia, rhyolite, andesite and tuff, so the selected The above four kinds of r...

Abstract

The invention discloses a preprocessing and segmentation threshold value determining method of volcanic CT images. The method comprises the following steps that volcanic CT sampling is conducted; the volcanic 2D CT images are collected; 2D CT image data are preprocessed; the images are superimposed to form a three-dimensional data body; a three-dimensional reconstruction body binaryzation threshold value method is improved and determined; a three-dimensional reconstruction model of the volcanic CT images is built, and three-dimensional display is conducted. The method resolves the problem of the dimensional restriction of analysis of a volcanic storage space in the prior art, expands the application range of the CT technique, enables a large number of oil field researchers to quantitatively conduct three-dimensional reconstruction of the volcanic CT images more conveniently, and has scientificity and universality.

Description

technical field [0001] The invention belongs to the technical field of research on volcanic rock reservoir characteristics, and in particular relates to a method for preprocessing CT images of volcanic rocks and determining a segmentation threshold. Background technique [0002] Since Roentgen discovered X-rays in 1895, CT technology has developed rapidly. In the following hundred years, many imaging technologies have been developed, such as computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography. technology (PET), single photon emission tomography (SPECT), ultrasound imaging. [0003] Computed tomography (CT) is a non-destructive detection technology that can detect changes in the internal structure of rock materials, and has become one of the important experimental methods for observing the internal structure changes and fracture evolution of rock materials. Raynaud (2008), Yang Gengshe (1999), Ge Xiurun (1999) studied the relationship...
